6. Slowly turn the X-axis hand wheel clockwise to move the table to the left.
As the workpiece approaches the edge finder it first forces the movable end
to become more concentric with the body.
7. When the movable end of the edge finder is almost perfectly concentric
with the body it will all of a sudden jump to one side and stay there.
The point at which the movable end of the edge finder jumps to one side is
the point you are looking for. Stop turning the X-axis hand wheel at this
point.
8. Turn the motor off.
9. Raise the mill’s head so that the edge finder is completely above the
workpiece.
10. Set the X-axis dial to zero.
11. Turn the X-axis hand wheel clockwise 0.100”. If your dials have 62.5
divisions, you turn one full turn plus 37 and one half divisions. If your dials
have 50 divisions, you turn two full turns.
The movable end of the edge finder is 0.200” in diameter, so you are
moving the distance from the center of the edge finder to the edge of the
workpiece.
12. Zero the X-axis dial.
13. Note the location of the pointer relative to the X-axis scale across the front
of the table. You may want to rotate the pointer so that it aligns with one
of the tic marks on the scale.
This is the zero point for your X-axis movements.
Drilling
There are several ways to locate the position at which you want to drill a hole.
You can use your layout tools to scribe crossed lines at the hole location, and
then use a wiggler to align the mill’s spindle over the intersection of the
scribed lines.
You can use an edge finder to locate two edges of the workpiece, and then use
the X- and Y-axis hand wheels and dials to locate the correct location.
Once you find the location, start the hole with a center drill or spotting drill.
These specialized drills have relatively large diameter shanks to prevent
bending or wobble as you start the hole. This ensures that the hole is located
directly below the center of the spindle.
Next, drill a pilot hole about 1/8” in diameter (but not larger than the final
size you need).
Finally, drill to the final drill size you need. You can drill the final hole size as
long as two conditions are met. First, the web of the drill bit (the short straight
section at the very tip of the drill) must fit into the pilot hole. Second, the drill
must not be too large for the mini mill to drive. If power is an issue, use
smaller drills to reach the final diameter in steps.
